iPhoneS 3.1.3 is now out from Apple. Supposedly it fixes some battery issues. (Doesn't every release make things faster and fix battery problems?) There are no new features. The release only stops jailbreaks. That’s right. No new features.

DO NOT UPDATE YOU WILL BE SORRY.

Currently there is no jailbreak for this firmware. Unofficial sources have confirmed that they have patched up the method we used to jailbreak 3.1.2 so you will not be able to jailbreak. If you update you will lose all your jailbreak apps and will not be able to get them back. In other words, updating means you lose a lot of stuff in return for almost nothing back. In addition, there is no ETA on a jailbreak for 3.1.3. It may never be jailbroken. It is likely that they (dev team, geohot) will not waste another hole on 3.1.3. They will most likely hold it for the bigger update that will come with the release of the iPad and iPhone 4.0.

One more thing, as of right now, Apple is still signing 3.1.2 for you 3gs users but no one knows for how much longer they will be. Make sure you *rush* into Cydia or Rock and get your keys signed on the front page if you have not. This will make certain you can always restore 3.1.2 even in the future using Saurik’s server
